Need help on this question. Please explain to me :? Thanks


Mr Lim packed 387 apples. Each apple had a mass of about 24g. He put them into three different baskets. The mass of apples in the Basket A was 3 times that of the apples in C. The mass of apples in Basket B was twice that of the apples in Basket C. The mass of the empty Basket C was 140g. What was the total mass of Basket C and the apples in it?

The mass of apples in Basket B was twice that of the apples in Basket C. The mass of the empty Basket C was 140g. What was the total mass of Basket C and the apples in it?

Let me try :
Basket A ~ 3 units
Basket C ~ 1 unit
Basket B ~ 2 units

Total Units = 6
Total mass of apples = 387 * 24 = 9288g
I unit = 9288/6 = 1548
Hence TOtal mass in Basket C is 1548 + 140 = 1688g. Appples alone is 1548g.

Joel & Ramah have the same amount of money. After Ramah gave $52 to Joel, Joel had twice as much as Ramah. How much money did each of them have at first.

In the end:

Joel = 2x
Ramah = x

Before the transfer:

Joel = 2x - $52
Ramah = x + $52

2x - $52 = x + $52

2x = x + $104
therefore: x = $104

So, in the beginning: they each had: $104 + $52 = $156

Hope that helped

Hi Tianzhu,
Your solution is so beautifully done. Not just mathematically but also artistically. May I know how did you so that?!
